Duprate has published a 32-bit Compatibility SFS for VoidPup64. Link from here, viewtopic.php?p=48613#p48613. Thanks again, Duprate.
The link from that post will take you to his google-drive where you'll also find a version of the portable-wine.sfs, and an SFS that includes both 32-bit Compatibility and Wine.
I already have portable-wine 'fleshed-out'. So I loaded his 32-bit Compatibility SFS, then registered my portable-wine. I was pleased to find that everything worked.
Under VoidPup64, with the 32-bit compatibility SFS loaded and portable-wine registered, only 372 Mbs of RAM --not including cache and buffers-- were used on boot-up; that is only 372 Mbs of RAM were not available for other work.
